Zapata County · La Perla (Lobo Cons.) field · Producing · Vertical
La Perla #42 (API 42-505-31505) is a well in Zapata County operated by Hilcorp Energy Company, completed March 22, 1993 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 1982 and 1992, permitted to 9,740 ft.
It was permitted by Transamerican Natural Gas Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 3 formation tops, including Wilcox, B/Wilcox, Wills Point.
Its 2 leases have reported 9 barrels of oil and 314K mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
